The plea arrangement was accepted by McHenry County Judge Sharon Prather.

The sex acts occurred while Hoerauf was living with two girls, who were not related to him but otherwise were known to him, who were between the ages of 6 and 9. The incidents happened between 2005 and 2007 either when Hoerauf was baby-sitting or when no other adults were around, prosecutors said.

He was charged in January.

Hoerauf told one victim that if she didn't submit to the sex acts, she wouldn't get presents from Santa Claus or the Easter Bunny, Assistant State's Attorney Sharyl Eisenstein said.

When interviewed by a McHenry County Sheriff's deputy, Hoerauf reportedly admitted to the sex acts and said he "couldn't believe it went on this long without getting caught," Eisenstein said.

Hoerauf must serve a 10-year sentence on the predatory criminal sexual assault charge followed by a five-year sentence for aggravated criminal sexual abuse. He will serve a combined five years on parole after his release and register for life as a sex offender.
